STRESAU FEED MILLING APPARATUS Filed May 15, 1929Patented Jan. 12, 1932 UNITE STATES PATE'FN' m RICHARD STRESAU, OF WAUWATOSA, WISCONSIN, ASSIGNOR 'IO SWIFTON MANUFAC- TUBING COMPANY, OF WESTALLIS, WISCONSIN, A'CORIPORATION OF WISCONSIN FEED-MILLING Arr-AsiansApplication filed May 15,

The invention relates to a feed mill for cutting fodder, grinding grainor other similar purposes.

The object of the invention is to provide a feed mill having a unitaryhousing with provision for removing the cutter shaft from one side ofthe machine to permit ready removal of the cutter or beater from thehousing, the present construction embodying certain modifications in thecutter or beater assembly for accomplishing this purpose over that of mycopending application, Serial No. 844,018, filed Mar. 2, 1929. y

Theinvention further consists in the several features hereinafter setforth and more particularly defined by claims at the conclusion hereof.

In the drawings Fig. 1 is avertical sectional View through a feed millembodying the invention;

Fig. 2 is a vertical sectional view taken on the line 22 of Fig. 1;

Fig.8 is a sectional view taken on the line 3-3 of Fig. 2.

Referring to the drawings, the casing 5 is formed as a unitary structurehaving side plates 6, upper cover plate 7, front plate 8 and lower rearplate 9, the plates 7, 8 and 9 preferably being welded to the sideplates 6 and the plates 8 and 9 being welded to a channel frame member10 which, with the lower ends of the side plates 6, is welded to metalskids or runners 11, one on each side, having tubular tie-bars 12 weldedthereto. This casing is provided with a front opening 13 and a rearopening 14. The opening 14 is normally covered by a removable door 15which is formed of plates'16, angles 17 and tubes 18. The lower'end ofsaid cover fits in a recess 19 provided in a bar 20 welded or otherwisesuitably secured to the upper end of the plate 9, whilethe upper end ofthe cover rests against the lower end of the cover plate 7 and is heldthereagainst by suitable fastening means. tween the side plates 6. Thefastening means may comprise bolts or pins 21 mounted in the tubes andengageable in apertured lugs 22 secured to the side plates 6. The termunitary casing is used todistinguish thisconstruc- The cover fits snuglybe- 7 1929.

the roller 24 being a driven roller,maybe used to feed the material intothe machine past the revolving cutter .25 whose construction. andassembly on its shaft 26 is similar to that of the cutter or beater 27associated with the screen 28 and shown in detail in Fig. 2.

Referring to Fig. 2, the cutter or heater 27 is formed of a plurality ofbeater, hammer or cutter members 29 and. spacing washers 30 that aremounted on a tubular'shaft: 31 and 5 clamped thereon and together byspanner nuts 32 mounted-on the threaded ends 33 of said shaft. A washerat each end of the shaft isprovided with acounterweightportion 34 sothatafterthemachine is assembled these washers may be angularly adjustedrelative to the shaft to properly counterbalance the same. 1 I

The sleeve or shaftiil has spacedkeys'35 '7 inset thereinvand Weldedthereto and engage- 7' 1 able in aa-longitudinally extending key-way.3,6 in the drive shaft37 which, as hereinafter explained, is removableendwise from the housing 5 so that the beater 27 may be slipped off ofsaid shaft and removed through the so opening 14. When assembled'theheater or cutter. assembly is held against longitudinal movementrelative to the shaft 37'by'set- 1 screws 38. r

,The shaft S'Zlhas a reduced end portion 39 S5 slidably mounted in asleeve 40 which in turn 1s secured to the inner race of a ballbearingjournal41 whoseouter race is mounted and held within abearing block42secured to one of the si'de plates The outer end of the 90 part 39 hasa suction fan 43, disposed in a casing 43, secured vthereto by akey-lock washer 44 and nut 45 and its hub 46 fits over a portion of thesleeve 40. i

The rear end portion 47 of the shaft37 is 95 journalled in aball-bearing journal 48 those inner race'is secured to said shaftbetween a shoulder thereon and thehub of a gear 49 associatedwith otherparts of the machine and whose outer race is mounted within a bearingsupport 50 between a flange 51 and a removable collar 52. The bearingsupport is detachably secured to the adjacent side plate 6 so as to beremovable with said shaft and the bearings 48 by means of suitable studs53 secured to said side plate 6 and nuts 54. The shaft carries a drivepulley 37. With this construction, taking off the nuts 54 and the nut 45and fan 43 and loosening the setscrews 88 permits the shaft 37 to beremoved endwise from the housing and through the shaft 31, whereby thebeater may then be taken out through the opening 14.

The same general arrangement is carried out in connection with theassembly of the cutter 25, whose drive shaft 26 is removable endwisefrom the housing similar to the shaft 37 and has a slidably keyedconnection with a tubular shaft 55 upon which the cutter blades 56 arespaced, mounted and secured in the same manner as the beater blades orcutter blades 29.

Further details of construction of the ma chine are not deemed necessaryas the invention here involved is confined to the combination with aunitary casing of a cutter or beater assembly of the character abovedescribed.

I desire it to be understood that this invention is not to be limited toany particular arrangement or construction of parts except as suchlimitations are specified in the claims.

What I claim as my invention is:

1. In a feed mill, the combination of a housing, .a drive shaft mountedin said housing, a feed reducing device including a tubular shaft, feedreducing blades associated with said tubular shaft, and adjustablecounterweights mounted on said tubular shaft.

2. in a feed mill, the combination of a housing, a drive shaft mountedin said housing and removable endwise therefrom and provided with akey-way, a tubular shaft fitting over said drive shaft and provided witha key engaging in said key-way and with threaded ends, feed reducingblades fitting over said tubular shaft, spacing members fitting oversaid tubular shaft and interposed between said blades, some of saidmembers provided with balancinglugs, and nuts engaging the threaded endsof said tubular shaft for clamping said blades and spacing members inassembled relation.

In testimony whereof, I affix my signature.-

RIOHARD STRESAU.
